3500HD towing my latest project, a 60 Cadillac ambulance. Its a 21' long car on a 22' trailer, with about 2" to spare on either side!
Had I known what an awesome package the 3500HD is, I would have switched from a regular 3500 years ago. Much better brakes, gearing and suspension. Unfortunately the 7.4 gasser doesn't tow like a diesel, but I just have to go a little slower on the hills.
